Yale-Brown obsessive- compulsive scale (Y-BOCS) |
Y-BOCS maps symptoms and measures severity of obsessive-compulsive symptoms by a clinician. Y-BOCS has a range between 0 and 40 points, higher scores denotes worse symptoms. Outcome is measured as change in Y-BOCS score from baseline. At least 35% reduction in the score since baseline is defined as a response. |

Personal and Social Performance Scale (PSP) |
Personal and Social Performance Scale (PSP) gives a score for disability. The PSP is a 100-point single-item rating scale (range 1-100), subdivided into 10 equal intervals. Lower scores denote lower functioning. The ratings are based mainly on the assessment of patient's functioning in four main areas: 1) socially useful activities; 2) personal and social relationships; 3) self-care; and 4) disturbing and aggressive behaviours. Change in score between enrolment and week 40 will be measured. |

Clinical Global Impression-severity (CGI-S) scale |
CGI-S is a clinician rated measure of overall clinical severity that is rated on a scale between 1 and 7. A person with no clinical complaints or problems will get a score of 1. The score 7 indicates the highest level of severity is phrased as "Among the most extremely ill patients". |

Clinical Global Impression-Improvement (CGI-I) in relation to inflammatory markers |
Clinical Global Impression-Improvement scale (CGI-I) measures change of symptoms on a 7 point Likert scale. A CGI-I score of 1 or 2 corresponds to be much or very much improved. Change in inflammatory markers in blood (gene expression and proteins) towards normality, in relation to clinical response (assessed by the clinician) will be measured. |

Changes in cognitive functioning |
Improvement in cognitive tests using a subset of tests included in Wechsler Adult Intelligence Scale (WAIS) (i.e. Block design, digit span, letter number sequencing and digit symbol coding, visuospatial test). |

CGI-I in relation to treatment and evaluated by the treating clinician, the patient's self-assessment and a next of kin |
Clinical Global Impression-Improvement scale (CGI-I) measures change of symptoms on a 7 point Likert scale. A CGI-I score of 1 or 2 corresponds to be much or very much improved. Three different informants base their CGI-I evaluations on independent assessments: a) The treating clinician, b) The patient's self-assessment and c) A next of kin. Range 3-21. A lower score depicts larger improvement. |

B cell subpopulations in relation to clinical response |
B-cell depletion at week 5, and B-cell subpopulations at week 20 in relation to clinical response (CGI-I) (assessed by the clinician) and baseline levels of B-cells. |

Life quality measured with Brunnsviken Brief Quality of Life Scale (BBQ) |
BBQ is a 12-item self-rated measurement of life satisfaction, it is a likert scale, range 0-48. Higher scores denote higher life satisfaction. |

Clinical Global Impression-Improvement (CGI-I). Proportion of responders. |
Clinical Global Impression-Improvement scale (CGI-I) measures change of symptoms on a 7 point Likert scale. A CGI-I score of 1 or 2 corresponds to be much or very much improved. Three different informants base their CGI-I evaluations on independent assessments: a) The treating clinician, b) The patient's self-assessment and c) A next of kin. If the mean value of these three is below 2.5 then the patient will be regarded as a responder (representing much or very much improved since baseline). |

Adverse event: Any Adverse Reactions (AAR). Safety and tolerability of Rituximab |
Any Adverse reactions (AAR) is a rating scale developed for this study and is not a validated questionnaire. It consists of a list of 26 symptoms. AAR maps adverse events related to rituximab treatment. These items are assessed for severity on a Likert scale (4 levels: none; mild; moderate; severe) and frequency (3 levels: occasionally; daily; several times daily). AAR is assessed by the clinician. An adverse event scale was required as an outcome measure by the Swedish Medical Products Agency. |
